CHANNING M. THOMPSON, OF NEWARK, OHIO} HOSE-CLAMP. T

Specification of Letters Patent. jpplioation filed December 27, 1905. Serial No.- 298,501.

, HoseClamp, of which thefollowing is a specification.

This invention relates to clamps, and is primarily designedfor use as a hose-clamp for clamping hose-pipes to the metal fittings thereof. i

It is an important object of the present invention to materially simplify the clamp and to facilitate the application and removal.

thereof without liability of injury to the clamp and the hose in order that the device may be repeatedly used..

Another object of theinvention is to insure the snug contact of the. clamp through the eriphery of the hose, thereby to prevent buc ing of the hose by the action of the clamp and to maintain continuous contact between the hose and its fittings.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and'minor details may be made within the scope of the claims without departing from t e spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a side elevation of'a hose-clamp of the present invention applied to a hose. Fig. 2 is a face view of Fig. 1. Fig. 3 isa-pers ecti've view with the members of the clampetached. Fig; 4 is a view similar to Fig. 1, showing a somewhat simplified embodiment of the invention. Fig. 5 is a face view of Fig. 4. Fig. 6 is a perspective view of the members of the sim plified form of the invention.

Similar characters of reference designate corresponding parts in all of the figures of the awings.

As embodied in Figs. 1 to 3, inclusive, the present invention includes two members (des lgnated in general A and 13,) each of which is formed from a strip of plate-metal. The member B is bent to a proximate a semicircle and preferably slightly exceeds a semicircle. One end of this member is'bent outwardly into an a proximately radial ear 1',

which is pierced y an opening 2 in the na= ture of a slot or elongated opening exten longitudinally of the ear. 7 The other en portion of the clamp member is provided with a slot, as at 3, which is preferably a bifurcation, said bifurcation extending slightly Patented Oct. 2', 19cc.

less than one-half the length of the member,

there being another longitudinal slot/1 between the slot 3 and the member 1 with a cross-bar or web 5 between the two slots. While the slot 3 has a mechanical function,

' as will be hereinafter described, the slot4 is primarily intended to reduce the weight of the device and also to increase the fiexlbility of the clamp member, while the web or crossbar 5 is intended to connect and thereby brace the longitudinal sections into which the clamp member is divided by the bifurca tion and the slot. What will betermed the inner end of the clamp member has its sides or sections bent. back upon the exterior thereof to form duplicate parallel hooks 6. g

The clamp memberAis folded intermediate of its ends to produce inner and outer portions 7 and 8, the bend 9 constituting what will be termed the inner end of the memher. The outer portion of this member is notched or cut away in its opposite edges, as indicated at 10, and the inner portion 7 is reduced in Width to ap roximate the width of the portion 11, whic lies between the two notches 10, Below the notches the outer section of the member retains its full width, and thereby roduces lugs or projections 12, which extend upwardly a suitable distance from the inner end 9. the member has its full width, as at 13, and is then bent outwardly to form an ear 14, having its extremity bent backwardly and outwardly, so as to form an overhanging flange 15, there being an opening 16 forms centrally through the ear 14. It will of Above the notches 10 Y course be understood that the two clamp members are bent to form arcs of the same circle, and the reduced portion 7 isextended beyond the ear 14 to form a tongue 7, which is reduced or beveled upon its outer side and at its free extremity, so as to constitute a wedge.

In assembling the present device to clamp a hose, such as-shown at 17, upon a fitting the member B is. forced sidewise around a hose, and then the member A is assembled therewith by engaging the lugs or 1projections 12 with the hooks 6 and forcing t e member inwardly, so as to embrace the ortion 7 upon the hose. It will here be exp ained that the llO - width to fit the bifurcation 3 of the member v portion 7 is'of a width to fit in the slot or bifurcation'3 between the hooks 6 and is of a length to substantially span the space between the ears 1 and 14. A bolt 18 is then thrust through the o enings in theears 1 and 14:, first through t e opening 2 and then through the opening 16, a nut 19 having been previously'placed against the outef side of the ear 14 and into which the bolt 18 is screwed by means of a screw-driver or the like engaged with the slotted head of the bolt. It will here be explained that the overhanging flange 15 engages the adjacent edge of the nut and forms a lock therefor to facilitate the engagement of the bolt with the nut and to prevent turning of the latterafter the clamp has been assembled. The desired tightness of the clamp 11 on the hose is obtained by ad justing the b0 t 18 so as to draw inwardly the.

free ends of the clamp members. As clearly indicated in Fig.2 of the drawings, it will be noted that the inner reduced portion 7 of the clamp member A forms a continuation of the clamp member B, wherefore the clamp is in contact with the hose throughout. its entire external periphery, whereby a snug clamping of the hose is insured and buckling of the upon the fitting is prevented. By having the extremity of the tongue'portion 7 beveled or wedgeshaped it is designed to enter between the hose and-the clamp member B under the tightening action of the bolt 18, whereby that portion of the hose which lies between the ears 1 and 14 is embraced by the clamp, and when the part 7 a is forced in between the member B and the hose there will be a wed action to more snugly grip the clamp upon the hose without drawing an r portion of the clamp out of engagement with the hose. The clamps can be very readily removed b first removing the bolt- 18, then removing themember A by moving the latter downwardly, so as to disen age the lugs or projections 12 f1'om the 1100 the two clamp members can, be withdrawn from the hose without damage to the latter or to the clamp members.

The embodiment of the invention as disclosed in Figs. 4, 5, and 6 of the drawings includes two members A B,'the member B being' a duplicate of the member B shown in Figs. 1, 2,.and 3 and hereinbefore described.- The member A has a shank portion 20 of a B, its inner end being bent back, as at 21, and of a width exceeding that of the shank 20, so as to produce wings or projections22,

extending at opposite edges-of theshank and outer sidethereof. The

in width, as at 23, and is bent outwardly to form an car 24, which has its extremity bent back to form a transverse flange 25, corre sponding to the flange 15 of the first-described form of the invention. 1 A tongue 26 ose 'members, one of t 6, whereupon is cleft fromthe ear 24, so as to produce an opening 27 the tonguebeing bent inwardly to form a continuation of the arc of the shan 20, with its free extremity beveled.

The simplified form of the invention is as- .sembled in the manner hereinbefore described for the form shown in Figs. 1, 2, and 3, the ears 1 and 24 being connected by a bolt 18 and a nut 19, so as to clam the members firmly upon the hose, which as been shown The advantage of? the simplified form of the invention resides in the fact that it requires about half as much material for the member A as is required for the member A, 'while at the same time it has all of the functions of the member A.

Having thus described the invention, what is claimed is 1. A hose-clamp comprising twoarcuate members, one ofs aid members having outwardly-directed hooks atone end and an ear at the other end, the other of said members having an outer portion formed at one end with projections to engage the hooks and at the other end with an ear, said other member also having an inner portion located between the outer portion and the hose and forming a tongueextending across the space between the ears.
